Modular Vision 7 MX93
Flashing Modular Vision 7 MX93
The Modular Vision 7 MX93 device follows the generic sequence, with some steps modified.
The instructions provided below refers to the usage of UUU tool under Linux OS. The same instructions can be applied to Windows by using the uuu.exe executable variant instead. Any bash commands on any part of the guide can also be replaced by their respective Windows commands.
Software Requirements
Please download the artifacts according to the generic sequence. Only the U-Boot and Image (wic.bz2) artifacts are needed.
Please follow the instructions on unpacking the U-Boot artifact, and check that the "imx-boot" file has been unpacked.
Hardware requirements
A connection with the serial port of the device needs to be made, in order to enabling flashing the device with the image.
Please follow the "Prepare USB Connection to the device" procedure of the generic NXP flashing sequence.
Flashing Instructions
The "Serial Downloader mode" section of the generic procedure can be followed. A safer alternative can be found below. This alternative is recommended as it does not alter the eMMC's contents.
The boot sequence must be interrupted with a keypress in the debug console, in order to get access to the U-Boot prompt. The command line will look as follows:
MX SECO U-Boot >
Run the following command in the U-Boot terminal:
fastboot 1
The device has now entered Serial Downloader mode, and will seem unresponsive. Upon power cycling the effect of this command is reverted, and the device's eMMC contents are unaffected. One can simply repeat this procedure to enter Serial Downloader mode again.
The commands described in the generic sequence can also be used, but are not recommended. Please heed the warning on the generic instructions, that by using those commands instead the device will not be able to boot until a new bootloader has been flashed.
The flashing command itself needs to be adapted as such:
sudo uuu -b emmc_all imx-boot ./seco*clea-os*roots*.wic.bz2
After issuing the command, the flashing operation will initiate and a progress bar will appear. Once the operation is finished, the terminal on the host side will look as such:
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.201-0-g727fc2b
Success 1 Failure 0
3:12-4B4725E 8/ 8 [Done ] FB: done
The device is ready to use and will boot to Clea OS after performing a power cycle operation.
